No, he was all but bankrupt.
That's why he took a role in a stupid sitcom.
People said the same about Mickey Rooney but he had something like $16K when he died.
I suspect you're correct about the money problems. He'd been trying to sell his Napa estate for a long time - big price cut earlier this year.

The "stupid sitcom", however, made him a star...and I don't think he regretted doing the gig.
Still, Williams could snag a few million each for a couple of movies and move on.
I doubt this was about money, and more the demons in his head.
Why is it that so many good comedians are tortured in their hearts and minds? Is that what makes them so good? The comedy that keeps them going in their heads then share with us, is that why they have that gift?
I realize I don't really know this guy or any Hollywood actor, but when it is someone that has made you feel good and laugh so many times, it connects deeper and harder to see them go.
God bless him, I hope he has finally found peace.
